More evidence of global warming contributed to by your filthy car
exhausts?

"The destructive intensity of the winds caused by tropical storms and
hurricanes has increased significantly in the past 30 years, in line
with the theory that cyclones are becoming stronger because of global
warming, scientists said yesterday.

A study of satellite data going back 25 years has found that tropical
storms in the North Atlantic and the Indian Ocean are getting
significantly stronger and therefore more likely to develop into
hurricanes with wind speeds greater than 100mph.

The findings support the idea that the ocean acts like a "heat engine"
driving tropical cyclones. The theory is that as more heat builds up
in the oceans, the more energy there is to become converted into the
strongest winds of hurricanes.

In 1981, the average wind speed of 90 per cent of hurricanes monitored
globally by satellite came to 139 mph but, by 2006, that speed had
increased to 157mph, said Professor James Elsner of Florida State
University in Tallahassee..."
